,Minnesotxn have invented Ynew and useful Improvementsin Machines for Making Lath- Board, of which the following isla specifico,- tion.

This invention relates to a machine adapt- 4seserete means that v vvill form the paper into ili'erentshape. With ,these and incidental ob]ects in view the invention consists in certain novel features of' oonstruotiony and combination oat-v fadapted to receive the ends of the .piercing pins 24 during the operation ofthe ma I parts, the essential elements of which nre set forth in appended claims :md a preferred form of embodiment of which is hereinafter described with reference to the drawings ,which accompany and form a part of ythis specification.

-`To operate the machine, the pulley l10 is revolvedin alfclock-wise direction by any suitable means,--not shown, thus continuously car ying thechains -13 and 14 with their forrlng cleatsas an endleA belt, traveling over the lowerfsets of sprocket Wheels.

In operating. the machine, suitable paper or other material 27 is fed in While the machine is running, and this paper will he carried by the cleats 23 down against the lower drum. 26the pressure between the two surfaces 'holding the paper firmly. The next cleat 17, traveling upwardly, will engage the paper and bend` it at an acute angle against the angular surface of the cleat 23 at that time associated with it.

The fold thus formed is carried forward, and the succeeding cleat 23 will press 'the paper over the edge of the cleat 17 just preceding it, the paper at that time bein pressed by the upper surface of the cleat l firmly against the upper drum'26.

It is evident between the adjoining edges of the two forming cleats, the piercing points of 24 25 and pierce the paper at `that point on both :sides of the upper cleat, and the paper formed into a plaited form with the perforations' made and the piercing-points remaining inv ythe will be carried horizontally the point X is reached, When the formin cleats will disengage themselves and leavet e paper formed, as shown at Y with thecorner designated as A, so stretched if so desired, be readily returned to the form which it had while traveling through the machine.'

As the forming of the paper into the plaited form is accomplished directly by the two setsof chains carrying the forming cleats, it is evident that by merely 4changing 1, for chains simi- :forward u ntil be formed into a rectangular corrugated shape, as illustrated in Fig. 2.
